Left 4 Dead 2

People celebrate Halloween in different ways. Some dress up as their favourite character, some turn their houses into haunted dwellings, and some light firecrackers and scare my dog. For modder Yogensia, however, Halloween is a time to celebrate by creating iconic horror movie weapons for use in Left 4 Dead 2.

"I still enjoy the idea of adding new [mods]," he said. "It's all about finding something that piques my interest and matches my skills, then finding free time to work on it.

"I'll most likely work on Negan's baseball bat 'Lucille' from The Walking Dead in the next few weeks."

The work Yogensia puts into each mod can take anywhere between a few hours to several weeks depending on how ambitious the project is. He tells me that the "workflow is not set in stone," and that every modder has a different way of doing things. His method starts with him modelling a high-polygon version of the featured weapon, making sure to focus on as much detail as possible.

"After that, I simplify the model to make it low-poly and usable in games, making sure the general shape still looks relatively good," he continued. "Then I do a process called 'Baking,' which transfers the details of the high-poly model to the low-poly one as textures.

"This makes the low-poly look almost as good as the high-poly from a normal viewing distance. Then I start texturing the low-poly model, and finally I convert the model to the game's format, make sure it works properly, and upload it."

Sometimes you just want to be sure you aren't missing any small details

Yogensia

Before actually modelling and creating the weapons, Yogensia says he spends a lot of time doing research and looking at pictures for reference. He tends to stick to shots from the movie itself since "Google searches tend to show a lot of cosplay props or replicas with missing details and inaccuracies."

"Axes and machetes are relatively simple, but sometimes you just want to be sure you aren't missing any small details," he explained.

Of all the iconic weapons created by masters of design and armory, Yogensia singled out the M41A Pulse Rifle from Aliens as his white whale. He's worked on a model of it for the last couple of years, taking his time and care to make sure it's as accurate as possible.

"Sci-fi rifles are, of course, more complicated than melee weapons, and if I ever release an Aliens-related mod, I'd like it to be up to the standards of the first two movies," he said.

Overwatch is no exception, and four months after launch, 51 Overwatch asset rips and mods have made their way onto the Steam Workshop, from D.Va s pistol to Torbj rn s hammer. I downloaded as many as I could and dove in.

The mods didn t necessarily have a transformative effect on my Left 4 Dead experience, but they do inject little moments of novelty. Each time you equip Soldier 76 s Heavy Pulse Rifle (M16), he does a salute gesture toward his visor and a portion of his ult sound effect plays. Ana s Biotic Rifle is a neat swap for the hunting rifle that makes it sound like a toy air gun.

The mods don t gel perfectly together: when I equipped Genji s katana, it created an issue with the Reaper model I was using in place of Coach, blocking part of the screen. The flashlight mod I used was comically bad, casting a barely-transparent projection of Widowmaker s face into the map.

What would really tie these mods together is if someone took a page from this TF2 mod and imported one of Overwatch s maps into Left 4 Dead 2 Route 66 seems like it could work pretty well, if some obstacles were added.

I don't remember which game we were playing, but it was the kind of Japanese RPG that listed everything you needed to know about its characters down the side of the screen. Magic points, coins, food, all summed up with helpful numbers. Only one of them was abbreviated: HP.

What does HP stand for in this game? I asked my friend, an expert on JRPGs.

Health pineapples, he confidently replied. You have to knock all the pineapples off before you can hurt someone.

HP, whether it stands for hit points, health power, or indeed health pineapples, is one of many mechanics to come to video games via the original tabletop roleplaying game Dungeons & Dragons. However, the idea of representing the amount of punishment a character can take with a discrete number of points is much older than D&D. And while we might all know what the abbreviation means, it turns out that what hit points are meant to represent isn't quite so obvious.

"They didn't care if they could kill a monster in one blow, but they didn't want the monster to kill them in one blow." D&D co-creator Dave Arneson

In a 2004 interview with GameSpy, D&D's co-creator Dave Arneson explained that the earliest version of the game didn't have hit points. The rules had evolved from wargames he and fellow D&D inventor Gary Gygax played, in which a single successful attack was all it took for a soldier to die.

That changed when they started experimenting with having players control individual heroes rather than entire armies, as players identified with them much more strongly. As Arneson put it, They didn't care if they could kill a monster in one blow, but they didn't want the monster to kill them in one blow.

Arneson had previously made his own rules for a naval wargame set during the Civil War called Ironclads, and together with Gygax had collaborated on a Napoleonic naval game called Don't Give Up The Ship! Both games had a mechanic that allowed for ships to take multiple hits before being sunk, which they'd borrowed from the wargaming rules designed by author Fletcher Pratt in the 1930s. They borrowed those rules again for D&D.

In his book about the history of simulation games Playing At The World, Jon Peterson explains why hit points were such an important idea: Hit points introduce uncertainty and variance [ ] In Dungeons & Dragons, even when the prospects of a hit are near certain, the damage dice provide another potential survival mechanism via endurance, another way of forestalling death and increasing the drama of combat.

From table to screen

Like D&D, video game combat discovered a new sense of drama with hit points. Early arcade games like 1978 s Space Invaders typically killed players with a single successful enemy contact, using multiple lives to prolong the experience. Replacing that with the ability to survive a set number of hits before dying added a finer-grained rise in tension. It removes the frustration of being reset to the start of a level every time a player is so much as brushed by an enemy, and as the number of hit points remaining falls your anxiety rises in direct correlation.

Being on your last life may make you cautious, but there's a smoother transition with hit points. You gradually shift between playing more carefully as you approach half-health, biting your metaphorical nails as it dwindles below that, and sinking into erratic risk-taking when only a sliver of life remains.

Video games inspired by D&D were the first to copy hit points, as far back as 1975 games PEDIT5 and DND, which were coded for the PLATO system designed by the University of Illinois. DND was also the first game to have bosses, who could have hundreds or even thousands of what it called Hits.

The first official adaptations of D&D to PC were the Gold Box series begun by SSI with 1988 s Pool of Radiance. They followed the rules of what was then called Advanced Dungeons & Dragons closely, which meant beginning characters had very few hit points. Playing around a table there s always the option to fudge dice rolls to prevent deaths from feeling too arbitrary, but the computer was never so forgiving and players got used to reloading frequently.

Games that weren t licenced had no such problem. The first Ultima began players with a tidy 150 hit points, and the second with 400. Important non-player characters like Lord British had totals so high that killing him became seen as a challenge, and by Ultima III players were luring Lord British to the beach so they could attack him with cannon-fire, as if he was one of the naval ships in the wargames hit points came from.

Arcade games tended not to represent hit points numerically, however. Memorably, in the platformer Ghosts 'N Goblins (ported to the Commodore 64 in 1986) Sir Arthur lost his armor on taking damage, continuing to fight in his underwear.

One of the first game to represent hit points with the now familiar life bar was Dragon Buster, a 1985 dungeon crawler by Namco with a Vitality meter that changed from blue to red as you took damage from its bats, snakes, and cave sharks. While red life bars would go on to become standard, other ways of visualizing hit points have been tried with varying degrees of success.

1983 ZX Spectrum/BBC Micro game Atic Atac had a slowly depleting roast chicken that tracked your starvation, and dinosaur fighter Primal Rage used veins leading to a heart that exploded at the moment of defeat.

Other games have tried to make their life bar a part of the game world, as in first-person Jurassic Park game Trespasser where it's a heart tattoo on the protagonist's breast you have to look down at to check. In sci-fi horror game Dead Space the life bar is represented by lights on the back of your armor, which would be very useful if you had a doctor standing directly behind you. Each of these visualizations is just a way of integrating a hit-point counter into the world, but in doing so they free the player from having to correlate a number with something that should feel real and immediate. They re all still the same old hit points, under the surface.

MIDI Maze

The true origin of BJ Blazkowicz and Doomguy.

MIDI Maze, a 1987 first-person shooter on the Atari ST, was an early example of both the deathmatch shooter and the idea of representing hit points visually. Each player was a floating smiley face, like a three-dimensional Pac-Man, and an icon of that face at the top of the screen became sadder as they took damage. Later shooters like Wolfenstein 3D and Doom would copy this idea, their protagonists' faces growing more bruised and bloody as they absorbed bullet after bullet.

The regeneration generation

MIDI Maze is an early example of another change in the way hit points worked, as it also had regenerating health. It wasn't the first, however. The action-RPG Hydlide, released on Japanese home computers like the PC-88 in 1984, gave players back hit points when they stood still. Where other games had food and first-aid kits that functioned as magically as the healing potions in fantasy RPGs, regenerating health though no more realistic at least took health items out of the game world. It made healing an abstraction like hit points are, rather than requiring players assume Johnny Medkit has wandered the world ahead of them scattering healing items like seeds.

It was Halo: Combat Evolved that popularized regenerating health, which is ironic because it didn't really have it. Halo's hero Master Chief wears an energy shield that regenerates after a short interval without taking damage, but once that's gone he has a traditional life bar that can only be refilled with medkits.

However, the recharging energy shield was what gave Halo its famous 30 seconds of fun that happened over and over and over and over again as designer Jaime Griesemer put it, letting players pop out of cover to shoot aliens and then duck back to recharge and reload, and that's what had a lasting impact.

The idea was copied and modified by plenty of other games. Call Of Duty has become the flag-bearer for regenerating health, taking the blame for its propagation though it wasn't introduced until the second game in the series. Even in the mid-2000s as it was first becoming widespread, regenerating health was criticized by old-school shooter fans for removing some of the drama and tension that hit points represent. It's still enraging comment sections today.

Three games released in 2005 and 2006 all tinkered with ways of making regenerating health retain the sense of rising tension that hit points were first introduced to create. Condemned: Criminal Origins, Prey, and F.E.A.R. all set a floor on automatic healing so that if you take enough damage to fall below around 25% of your hit points you can't regenerate back above that line. It models a difference between taking a serious wound and the kind of graze action heroes can just walk off, and adds grit to more serious games.

Regenerating health was criticized for removing the drama and tension that hit points represent.

When the Just Cause games toy with this, only letting you regenerate a percentage of the most recent damage you take, it can seem at odds with their over-the-top action.

Horror games have also tweaked the way they use hit points to suit the genre. Zombie game Left 4 Dead slows you down the more you're hurt, making it harder to run away from the infected as if you're a movie character being worn down by the chase. In Silent Hill 4: The Room you regain health in your apartment, but when that safe space becomes tainted it stops healing you, a mechanical sign of its corruption that ensures you feel the same dread the character would.

Back to the source

Still, across all of these games, what hit points represent isn't entirely clear. Are they purely the injuries you endure, as the suffering face of Doomguy suggests? If that's true why is it so easy to get hit points back, whether through healing items or regeneration or drinking Fallout's irradiated toilet water?

In The Lord of the Rings Online hit points are replaced by morale, which explains why singing a jaunty tune helps top it up. In the Assassin's Creed games it's synchronization, a representation of how accurately your digital simulation is recreating historical events although that raises the question of why being hurt during events where your historical analogue was also hurt doesn't improve synchronization.

Even in D&D it's unclear what hit points really are. In the Dungeon Master's Guide for Advanced Dungeons & Dragons 1st Edition, Gary Gygax wrote that hit points reflect both the actual physical ability of the character to withstand damage as indicated by constitution bonuses and a commensurate increase in such areas as skill in combat and similar life-or-death situations, the sixth sense which warns the individual of some otherwise unforeseen events, sheer luck, and the fantastic provisions of magical protections and/or divine protection.

(Charmingly, the rules then went on to explain that Rasputin would have been able to survive for so long because he had more than 14 hit points. )

Constitution, skill, sixth sense, luck, magic, and divine protection are a lot of things to bundle into one number, and raise further questions about why, for instance, poisoned attacks cause extra damage to your sixth sense . When asked about what hit points really are at conventions Gygax was dismissive, giving different answers to the question each time. Sometimes he said hit points represent the way swashbuckling movie heroes survive so many fights, or that they were an entirely meaningless number that represented nothing more than a way of making the game's combat more enjoyable for players.

That second answer is perhaps the best explanation. Given that hit points started out as a way of simulating the ability of a ship's hull to weather cannon-fire, it's only natural that there's going to be some vagueness and necessary abstraction when we apply that same concept to our video game heroes. They may as well be health pineapples, after all.

On behalf of our team here at PC Gamer, I'd like to thank modders for their tireless, passionatework this year. The community of hobbyists, mapmakers, modelers, and countless tinkerers we benefit from on PC have created great things throughout 2016. I invite them to take a break: we've found the only mod we need for the immediate future.

Molkifier, who has previously turned actual cannibal Shia LaBeouf into a Hunter, has repurposed another millennial celebrity's work in Left 4 Dead 2. The Jaden Smith Tweets mod replaces the wall scrawlings found in each of Left 4 Dead's safe rooms with some choice Jaden Smithisms, whose tweets often sound like they're the collaboration of a conspiracy theorist, a spoiled teenager, and a first-year philosophy major.

That prose, as it turns out, works so perfectly in the medium of Left 4 Dead's walls that it's practically canonical.

The smaller text above reads: "Currently Going Through Customs Even Though I Was Born On This Planet." This appears in Left 4 Dead's airport campaign, Dead Air.

Louis isn't buying it.

This inspirational message seemed to fall flat for Deadpool.

Some of the tweets, all of which are copied verbatim from Smith's account, genuinely sound like the scrawlings of a desperate person in the post-apocalypse, struggling to make sense of it all. "It's Okay To Cry Guys," one of the graffiti reassures. "I've Bin Drinking Distilled Water For So Long That When I Drink Normal Water It Feels Like I'm Swallowing Huge Chunks of Aluminum," another complains. The text "Who Was On The Plane" appears in Dead Air, and removed from Twitter it sounds a survivor looking for the answer to who caused the infected to spread to the airport.

Others walk the line between humor and believability. "Shia Labeouf Do Not Leave New York City Without Letting Me See You"; "I'm Slowly Realizing I Need To Make A Trip Out To Norway"; "I Don't Like To Tweet But The New Hunger Games is Literally Amazing."

Elsewhere, they're glimpses into the psyche of those who miss the world they lost. It's a uniquely successful parody: one that pokes at Smith's preachy aphorisms while remaining completely at home in the context of a zombie survival shooter.

TRIGGERNOMETRY

We write about FPSes each week in
Triggernometry, a mixture of tips, design criticism, and a celebration of virtual marksmanship.

There isn t enough poetry being written about guns. Not literal limericks or sonnets (that would be creepy), but words that dig into and capture what makes one game s AK-47 more fun than another s.

Weapon feel continues to be the nebulous catch-all for the nuances that make guns fun. Most of the reviews of shooters I read offer the same praise: guns feel great or feel really powerful. If the writer s being generous, they ll use a word like punchy to describe an SMG. I ve been guilty of this too during my six-year term at PC Gamer.

Months of work goes into designing, animating, and balancing the things that put the S in FPS, so maybe we should take a moment to talk about what makes a good gun good.

I think the visual design of weapons matters far less than we think it does. There s a tendency, probably because they re planted right in front of our perspective at all times, to think of guns as a collection of aesthetics: firing and reload animations, SFX, screen shake, particle effects, and the death animations they produce. Those things make a gun, right? So if those things are good, surely we have an interesting and fun video game weapon, right?

No. Consider the AWP: it s olive green, it s bland, and its simple animations are more run-of-the-mill than Rambo. The only aesthetically remarkable thing about the most revered, iconic, and infamous sniper rifle in a video game is that it s a bit loud. And yet
thousand-comment debates erupt when Valve tweaks the way the AWP s scope works. Why?

A gun s look and sound are part of its personality, sure. But if you ask me,
great video game weapons have meaningful, interconnected relationships with other game elements. Those elements differ from game to game, of course. In CS case, the appeal of the AWP is born from the fact that CS is an FPS with body-part-specific damage modeling and no respawns. In that context, it s the only gun that grants an instant kill if you tag someone above the waist.

That feeling of possibility is fun within the strict rules of CS movement: if you can hit it, you can kill it… but you also can t be moving too much when you fire. With that power comes responsibility, too. Killed players surrender their equipped weapon in CS, and stolen AWPs not only save your team $4750 but act as a kind of trophy. This is doubly the case in CS:GO, where a player s custom AWP skin reminds all spectators which irresponsible player allowed their AWP to fall into enemy hands. Buying an AWP, then, to some extent, announces to the rest of the server: I think I m a good enough shot to protect this valuable asset from the other team.

All of this makes the AWP a weapon with abundant meaning. Even its shortcomings (slow rate of fire, difficult to use in close quarters) are a source of fun: the
noscope is a revered skillshot.

In Tribes case, its weapons shake hands with its player movement really well, arguably the quality that defines it as an FPS. Again, like the AWP, the Spinfusor isn't visually extraordinary: it fires discs at a medium speed, and its animations and SFX are pretty modest. But the Spinfusor is the perfect fit, the perfect baseline weapon in a game where your targets are typically skiing along the ground at high speed. Its splash damage leaves room for error and its relatively slow travel time creates an exciting feeling of uncertainty as you admire your shot. Like throwing up a three-pointer in basketball, you get to experience that arc of Will it go in? It might not go in. It went in! as the disc travels toward its target.

The Fusion Mortar creates the same sort of feeling while operating as a parabolic siege weapon. The design of the weapons actually encourages you to spend as much time as possible in the air: the threat they pose encourages you to master movement to have the best chance of staying alive. In each of these examples, the weapons strengthen the meaning and significance of core systems like movement, damage modeling, or weapon purchasing.

When Valve resubmitted Left 4 Dead 2 for classification in Australia earlier this month, many wondered whether the company had plans to re-release the game. Well, anything is possible, but in the meantime if you own the censored version of Left 4 Dead 2 a free patch is now available on Steam which will grant you access to all the gratuitous violence you've been deprived of.

It's good news for Australians, as until now we've had to jump through hoops in order to play the unedited version. Originally denied classification in 2010 due to its extreme violence, the game was resubmitted for classification following the introduction of an R18+ rating back in early 2013. The patch can be accessed via the Left 4 Dead 2 Steam page over here in the 'downloadable content' section.

To make matters better, if you've never played the game before then it's currently available with a 75 per cent discount, which is nice. There's never been a better time to hack zombies to death with wrenches.
